*Specification to substance of terrestrial ecotoxicity.*

Terrestrial ecotoxicity affects terrestrial species and it is measured by the quantity of 1,4-dichlorobenzene (DCB) produced. **Table 1** shows that for every 1 kg of OPC produced, 0.4381 kg of 1,4 DCB equivalent is produced to the terrestrial body. The specification to substance of terrestrial ecotoxicity that contributed to the overall amount of DCB with 61.5% of copper is shown in **Table 7**. The rest of the percentage comes from heat/power generation, ammonia emission, break wear emissions, electricity and some other with minimal emissions. **Table 8** shows the contribution of different stages of production with copper having the highest percentage of 38.72% while Clinker and brake wear emissions, lorry are 16.6% and 16.47% respectively. The rest of the percentage comes from heat/power generation, ammonia emission, electricity and some other with minimal emissions.

Fossil resource scarcity results to unavailability of fuel resources such as oil, gas and coal energy. It thereby increases the cost of available ones. It is measured by the quantity of oil produced per 1 kg of OPC produced. **Table 9** shows that crude oil (43.7%), coal (43.2%) and natural gas (13.1%) are substances that are used up

which eventually result into scarcity. **Table 10** shows almost the same result with 41.57% Petroleum, Coal 37% and Natural gas 8.22%.
